Patches of ground where huts were burned down in southern Africa contain a key mineral that recorded the magnetic field at the time of each ritual burning. Those mineral records teach researchers more about a weird, weak patch of Earth’s magnetic field called the South Atlantic Anomaly and point the way toward a possible mechanism for sudden reversals of the field.

Rochester, whose fortunes have risen and fallen with the demand for futuristic technologies from former powerhouses like Xerox and Kodak, is looking for its next big breakthrough in the field of integrated photonics, a light science with the potential to transform communications, medicine and national defense.

A $610 million research and manufacturing hub dedicated to the science of photonics — the use of light in technology — will be developed in western New York, federal and state officials said Monday, which could mean thousands of jobs for the region.

How busy your social life is at age 20 — and how solid the relationships are that you make when you’re 30 — are factors in your well-being later in life, according to research from the University of Rochester.

The Department of Defense has picked Rochester as the location for a sought-after manufacturing hub focused on the field of integrated photonics, U.S. Sen. Charles Schumer said Wednesday, ahead of an official announcement.

In the new paper, published in the July 20 edition of Optica, University of Rochester researchers show that a classical beam of light that would be expected to obey Bell’s Inequality can fail this test in the lab, if the beam is properly prepared to have a particular feature: entanglement.

This has been a long time coming since the University of Rochester Medical Center began building the $145 million project in September of 2012. Administrators said they have rehearsed the move for weeks and it went incredibly well.
